The modern old combine harvester, or simply combiners, is a versatile machine designed to efficiently harvest a variety of grain crops. The name derives from its combining three separate harvesting operations—reaping, threshing, and winnowing—into a single process.
A combine harvester is a very useful agricultural machine that can harvest, winnow, and thresh rice, corn, wheat, sunflower, pulses, and other crops right out in the field. Harvesting crops in this manner in one operational process can save time as well as human labor, and bring down work costs for farmers. In addition, these machines can increase agricultural output since the harvesting is carried out in a more efficient manner, and this, in turn, can make farming more profitable.
